2 Claims.

This invention relates to portable cases and manifold supports for gasanalysis apparatus, and it is among the objects thereof to provide aportable case for mounting the buretteabsorption pipettes and levelingbottle in a convenient and accessible manner.

The invention has for a further object the provision of a portable caseconstruction 'proportioned to minimize interference with light andimprove visibility of the pipettes and burettes, and which furtherprovides sliding panels as side and partial top covers to expose themanifold support.

These and other objects of the invention will become more apparent froma consideration of the accompanying drawings constituting a part hereofin which like reference characters designate like parts, and in which:

Fig. 1 is a, view in perspective of a portable case embodying theprinciples of this invention;

Fig. 2 a front elevational view thereof with the cover removed;

Fig. 3 a view in perspective of the case illustrating the constructionof the uprights and manifold; and

Fig. 4 a cross-sectional view partially in elevation of the manifoldsupport.

With reference to Fig. 3 of the drawings, the structure thereinillustrated comprises a base I, and a pair of uprights 2 and 2a havinga, top 3 cut out at 4 and at 5 to receive extended top portions 4a and5a, Fig. 1, of sliding panel or cover members 6 and 1, respectively.

As shown in Fig. 3, the uprights are provided with slots 8 and 8a forreceiving tongues of the sliding panels 6 and I which in the closedposition rests on the base I, and on the shoulders 4b and 5b of theuprights.

A manifold support generally designated by the numeral 9 is providedwith cut-out portions In for receiving the necks ll of absorptionpipettes l2 and the neck I3 of the burette M, Fig. 2.

The support is further provided with drilled holes l5 for receiving theglass cocks l6, Figs. 2 and 4, which have the manifold tubing 11 formedintegrally with the wall thereof. Because of the cut-out portions 5 inthe uprights, the manifold support 9 is fully accessible and entirelyvisible, which is necessary at times to follow the flow of the liquidsthrough certain types of manifold.

By this construction there is no interference from above or from thesides of the case. A cross-piece I8 is secured to the uprights at someconvenient portion between the base and the top, to which is attachedthe pipette supports l9, as shown in Fig. 2. The cross-piece [8 maytermithe burette I4, a base 2| being shown in Fig. 3

for the burette.

When assembled with the gas analysis equipment as shown in Fig. 2, thesliding panels 6 and.

l are disposed in the grooves 8- to enclose and protect the equipmentand a handle 22 is provided for' carrying the case.

This construction effectively closes the case and protects the glassequipment from damage.

The narrow upright members 2 and 2a cause less obstruction to thepassage of light to the pipettes and other vessels, including theburette. The fact that the burette is less obstructed is important notalone from the standpoint of better accuracy of reading but it alsopermits the operator to hold the leveling bottle 23 closer to the waterjacket in establishing the correct gas pressure in the burette prior toreading.

The manifold construction described in connection with Fig. 3 eliminatesthe conventional pipe hanger supports and may be employed in portablelaboratory models where a clear view of the horizontal member of themanifold is desired.

alignment with said cut-out portions mounted in a manner to be exposedat the top and front of said case, and panels slidingly mounted in saiduprights and having extending tops interacting with said cut-outportions to completely clos the container in assembled position.

2. A container for gas analysis equipment consisting of a base, sidewalls and top, the side walls being cut-out at the top, a manifoldsupport extending across the top mounted to be entirely exposed to thefront and sides and at the top of the container, and panels at the frontand rear of the container having extending top portions fitted into thecut-out portions of the side walls to be contiguous with the outer facesof the top and side walls of the container.
